Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE EXTRACCION POR ELECTRODIALISIS DE UN COMPUESTO QUE COMPRENDE AL MENOS FUNCIONES PROTONABLES AMINAS DE UN MEDIO LIQUIDO. ESTA SE REFIERE MAS EN PARTICULAR A UN PROCEDIMIENTO QUE PERMITE EXTRAER Y SEPARAR AL MENOS LOS MONOMEROS QUE COMPRENDEN FUNCIONES AMINAS PROTONABLES DE UN MEDIO QUE PROCEDE DE LA HIDROLISIS DE POLIAMIDAS. EL PROCEDIMIENTO DE EXTRACCION DE UN MEDIO LIQUIDO CONSISTE EN PROTONAR LA O LAS FUNCIONES AMINAS DE LOS COMPUESTOS QUE HAY QUE EXTRAER POR AJUSTE DEL PH DEL MEDIO Y EN SEPARAR LOS COMPUESTOS POR PASO A TRAVES DE UNA MEMBRANA CATIONICA BAJO EL EFECTO DE LA CORRIENTE ELECTRICA. LA INVENCION ENCUENTRA EN PARTICULAR UNA UTILIZACION EN LOS PROCEDIMIENTOS DE REVALORIZACION DE LAS POLIAMIDAS TALES COMO EL PA 66, PA 6.
